Optimization of calcium carbonate content on synthesis …

One of the most important characteristic of aluminum foam is compressive strength, which is reflected by its impact energy and Young’s modulus. In the present research, optimization of calcium carbonate (CaCO3) content in the synthesized aluminum foam in order to obtain the highest compressive strength was carried out. The results of this study will be used to determine the CaCO3 content
